Remove iconv(), iconv_open() and iconv_close() symbols from libiconv.

These were FreeBSD specific aliases for libiconv(), libiconv_open() and
libiconv_close() that are now also provided by libc which complicates
writing configure tests that work correctly when both libc iconv and
libiconv are available.

Also, because the libiconv iconv.h header redefines iconv* to libiconv*
correct use of the header implies that the aliases aren't used.

The following ports needed fixes because there was something wrong with
the way they tried to detect or use iconv:

audio/deadbeef: Remove LIBICONV_PLUG from a source file.  It's a
compile-time option and should not be set in source code.

converters/libiconv:
- Remove const qualifier from iconv(3) to match POSIX:
  http://pubs.opengroup.org/onlinepubs/9699919799/functions/iconv.html
- Patch iconv.h to expose more GNU extensions when LIBICONV_PLUG is
  defined because the base system iconv supports these extensions too.

Add/remove patches to/from ports to call iconv with non-const arguments.

This breaks some ports on FreeBSD 10 because base system iconv.h still has
the const qualifier.  Fix this by letting USES=iconv add a build dependency
on converters/libiconv so ports can use its iconv.h (with LIBICONV_PLUG
defined) instead of the base system iconv.h.

This exposed some ports that link with libiconv when it is available instead
of using libc iconv.  In these cases one of the following changes has been

This library is designed to make it easy to write games that run on UNIX,
Win32, MacOS X and other platforms using the various native high-performance
media interfaces (for video, audio, etc) and presenting a single source-code
level API to your application. This is a fairly low level API, but using this,
completely portable applications can be written with a great deal of
flexibility.
